*Update* - looks like we crashed their servers (oops!) ... hang tight and hopefully they'll have things up and running soon.
Yesterday this thread popped up in our forums letting users know about a cool new service. While it may be a bit buggy, vuivision.com allows you to watch live streaming TV right from your device - with no catch! Simply point your browser to vuivision.com, agrees to their terms and you're done. You can currently choose from NBC, CBS or ABC. Some are reporting some sporadic usage, but give it a shot anyway (just not all at once or it may crash :-) ). The resolution isn't all that great, but it is only a few seconds behind the live feed on my TV. We'll have to see how long this service lasts (or stays free) but it definitely shows a ton of potential.
